Countercurrent chromatography (CCC) is an efficient separation technique without the solid support matrix, largely depending on the partition of two-immiscible liquid phases in the separation column. Since the helical coil planet centrifuge was invented in early 1970s by Yoichiro Ito, a series of coils columns, including spiral coils and conical coils columns have been developed for CCC separation. In this work, we introduced a new simple and efficient concentrical coils column for CCC separation, which was prepared by winding the whole polytetrafluoroethylene (PTFE) tube into the circular grooves from the rotation axis in the same direction. Once the PTFE tube filled in all space of one round of the circular groove, it was jumped into the nearby outer circular groove through the gap and until the whole groove was filled. The three same concentrical coils distributed on three disc-shaped holders were connected by the same PTFE tube to form concentrical coils separation column. The separation capacity was further investigated using ten tanshinones of the extracts of a Traditional Chinese Medicine Salvia miltiorrhiza Bunge as a model natural product. All results indicated that the concentrical coils column could hold satisfactory retention of the stationary phase, higher theoretical plate number and better resolution for CCC separation of more than ten tanshinones. It may be an alternative CCC column for non-targeted and targeted isolation of bioactive natural products.
